SPECIFICATION forming part of Letters Patent No. 402,165, dated April 30, 1889.

Application filed June 14, 1888. Serial No. 277,077. (No model.)

To @ZZ whom t may concern:

Be it known that I, ISAAC KINSEY, of Cincinnati, Hamilton county, Ohio, haveinvented ,u 4L is a cap or covering to place over the electro-magnet, binding-posts, helix-piece, support, and part of the hammer. Fig. 5 shows the bed-plate having an ordinary electro-m agnet, a bell attached, and coveringpremoved.

Similar letters of reference throughout the severaldrawings denote the same parts.

My invention consists in a new, cheap, and convenient way of constructing an electric alarm-bell, the bed-plate P being formed from any' sheet metal and having the helix-piece h and support h and the bell-post b formed up, and integral parts thereof, as shown in the drawings, Fig. 3, said bed-plate P having convenient holes punched throughit (Fig. 2) for the purpose of attaching the bell and the binding-posts c and c', the latter of which are insulated from bed-plate P by the interposition of some suitable non-conducting material, the helix-piece h and support h being formed up from the plate P, having convenient holes punched through them for the purpose of attaching' an ordinary magnet.

coil and bell-hammer, the edge of said plate P, at convenient places, aand a, being raised to allow the notches in cap C to iit over them and thus prevent its turning on the post p, to which it is secured with a screw or other suitable fastening. The binding-posts c and c are secured to t-he bed-plate by screws or any ysuitable fastening and insulated from the same by means of any. non-conductng material. The 'notches in the bottom of the covering C permit the Wires to pass through to the binding-posts c and c to connect in cir* cuit.

The advantage of my invention over the ordinary electric alarm-bell is that I construct the bed-plate ready for putting on the electro-magnet, bell, and all the attachments by three operations of the machinery-first, to cut out the metal bed-plate P to the proper form; second, to punch out thenecessary holes at convenient points to cut the helix-piece 7L and support h, Fig. 2 5 third, to form up the bell-post b, the helix-post h, and support h', Fig. By these operations the bed-plate is so formed that the ordinary electro-magnet, with the bell and hammer, the insulated binding-posts, and the post b for supporting and covering C, can be easily placed in position and attached to the bed-plate P by screws or other convenient attachments; and, further, my invention can ben constructed much more cheaply, and is va much more convenient form for using, it being smaller, and easily attached by means of screws or other fastenings through the holes in the bed -plate P to the place desired.

Having thus fully described my invention, whatI claim as new therein, and desire to obtain by Letters Patent, is

`As an article of manufacture, a metallic bell-plate formed integralwith the bell-post b and having perforated tongues h h struck out of the interior thereof and bent upward from said plate to form the helix and armature supports, respectively, and tongues a a, formed in the edge of said plate and bent upward therefrom to form lugs for holding a cover, substantially as and for the purposeset forth.

The foregoing specification of my invention signed by -me, this 11th day of June, A. D. 1888. A v
